How can businesses effectively balance the use of customer data to personalize self-service options with maintaining customer privacy and trust?

Businesses can effectively balance the use of customer data to personalize self-service options by being transparent about the data they collect and how it will be used. They should also give customers control over their data and allow them to opt-in or opt-out of data collection. Additionally, businesses can prioritize data security measures to protect customer information and build trust. Regularly updating privacy policies and ensuring compliance with data protection regulations can also help maintain customer privacy and trust.
